Now I’m recommending you keep the online version of this page bookmarked, not the offline version. If you downloaded the local version of BOL using the Microsoft Help Viewer technique, you don’t have the latest version of the topic (at least I didn’t as of 10/2/2012 and didn’t find a more recent update). This may get refreshed periodically, but to be safe I recommend you reference the latest version on MSDN and not risk working with stale information.
